The iconic winger believes his side has the right credentials to reach the final of Euro 2012 after his headed goal dumped the Czech Republic out of the tournament
Ronaldo, whose 79th-minute header secured a 1-0 win for Portugal in its quarterfinal encounter with the Czech Republic, hailed the maturity of the team, especially considering the difficult group it has progressed from.
"I think we played very well and created many chances," he told the BBC. "We know it's going to be difficult next game but we are ready, we are confident, the team is very mature so we are ready for the fight."
"I felt a big joy. We were worthy winners, we played better. In the last two matches, we hit the post twice, now we did it again... But the most important thing is the ambition and spirit in our squad. I scored one more goal and I am happy for that."
Portugal was grouped with Germany, Denmark and the Netherlands. Its only loss of the tournament so far came against Germany, which has won its first three games.
"Our path has been very difficult We have gone through one more stage," Ronaldo said. "Let's see who we will face in the semifinals. We have big hopes. But we must keep our feet on the ground and take one step at a time. We want to win our next match. Our goal is to reach the final."
Portugal will face either Germany or Greece in the semis.
"The most important that I score, the team win, the team play very, very very good and we are in the semifinals so the team is very happy for that," Ronaldo said.
